Revealing mistake: In the wizards versus werewolves special, it's painfully obvious Juliet is a stunt double when she fights and grows her wings.
Continuity mistake: In the episode with Alex at the art museum and Justin a teacher's assistant, as Alex is in the room with all the paintings, she puts a piece of rope around the door handles. Later on when Alex says, "Go ahead scream panic," we see Alex in front of the door, but the rope is gone, but the next time it shows Alex the rope is there again.
Continuity mistake: In the first episode where the Emergency Wizards appear, the Goblin has 4 legs. Almost every episode after that with the Emergency Wizards in it (except the episode "Harper Knows"), the Goblin has 2 legs.
Continuity mistake: In the episode where Alex tells Harper she is a wizard, when Harper is eating the kettlecorn, she drops it on the floor. In the next shot it vanishes.
Continuity mistake: When Max is filming his last dangerous stunt, the camera changes position in the background between shots.
Revealing mistake: When Alex's uncle comes to visit, Alex and her uncle are in a scoreboard watching a basketball game. Alex's uncle says a spell where everyone's head spins around, and you can see they are fake heads.
Continuity mistake: In the "Wizards vs. Werewolves" special, just as the Russos learn that Alex and Mason have gone to Transylvania, Max is playing on his Nintendo DS. He then flips it shut. The shot switches to Justin, Jerry and Teresa. They talk and the shot switches Back to Max, and you see him flip the Nintedo DS shut again.
Answer: Honestly I've been confused too. Thought the ones going down went to Justin's bedroom or to the station. Then the ones out the door went maybe to an elevator to those stairs I guess. Then the one to the side went to the lair But the freezer also leads to the lair or a secret spot sometimes too.
I think the ones in the sub shop go right up to a hallway in front of the loft, then the ones in the lair go to the bedrooms upstairs. Now there's a way to get to the lair from the loft and I believe it would be past the kitchen down to the hallway where we don't really see except in like one episode. Now what confuses me the most is the lair because when Harper finds out you see Alex using magic to open it into the lair but in every other episode you open it and it's the lair.
